Ceramic bonding anti-scouring material with zirconium added into submersed nozzle
The invention discloses a ceramic bond anti-scouring material with zirconium added to a submersed nozzle. The ceramic bond anti-scouring material comprises the following raw materials in percentage bymass: 40-60% of corundum particles, 15-35% of corundum fine powder, 0-5% of alumina micro powder, 3-8% of a metal powder additive, 5-10% of a binding agent and 2-4% of zirconium. In the ceramic bondadded with the metal zirconium, the metal zirconium can generate a zirconium oxide material at a low temperature (400 DEG C or above) under an aerobic condition to form ceramic bond; the chemical stability of the zirconium oxide ceramic bond is superior to that of a carbon-containing material which is only bonded by resin, and in a high-manganese and high-oxygen use environment, the zirconium oxide ceramic bond is formed due to oxidation of metal zirconium under a low-temperature condition, so that the zirconium oxide ceramic bond has obvious anti-oxidation and anti-scouring effects and betterperformance.
本发明公开了一种浸入式水口添加金属锆的陶瓷结合抗冲刷材料，包括以下质量百分数的原料，刚玉颗粒40～60%、刚玉细粉15～35%、氧化铝微粉0~5%、金属粉末添加剂3～8%、结合剂5～10%、金属锆2～4%。本发明中添加金属锆的陶瓷结合剂中金属锆在有氧的条件下在低温下（400℃以上）就可以生成氧化锆材料形成陶瓷结合，其化学稳定性要优于仅用树脂结合的含碳材料，在高锰、高氧的使用环境中，因金属锆低温条件下氧化形成氧化锆的陶瓷结合，防氧化抗冲刷效果明显，有更佳的表现。
